  • Detecting Inconsistency between Network Design and Current State Based on Network Ontology Bonsai

    Mori K., Kondo T., Teraoka F.

    Asian Internet Engineering Conference, AINTEC 2024    76 - 84 2024.08

    　View Summary

    Generally, a network administrator designs, constructs, and operates an enterprise network. Since inconsistency between the network design understood by the administrator and the actual network configuration might arise due to mistakes or errors, a method for automatically detecting such inconsistency is needed. The following four techniques are necessary for this purpose. (i) A machine-readable notation to represent the network configuration. (ii) A tool to write down the network design using the machine-readable notation. (iii) A tool to automatically detect the current network configuration and write it down in the machine-readable notation. (iv) A tool to compare the two outputs generated in (ii) and (iii). This paper employs the network ontology called Bonsai for (i). Bonsai can represent not only physical configurations but also virtualization technologies such as VLAN and overlay. This paper proposes three tools, nc-design, nc-detect, and nc-diff for (ii)-(iv), and confirms that they work as expected in the test network. This paper also measures their fundamental performance.

  • Poster: A Container Orchestration Method Considering Shared Containers in an MEC Environment

    MOBISYS '24: Proceedings of the 22nd Annual International Conference on Mobile Systems, Applications and Services (ACM)     698 - 699 2024.06

    Research paper (international conference proceedings), Joint Work, Last author, Corresponding author, Accepted

    　View Summary

    In a Multi-access Edge Computing (MEC) environment, an application will be composed of multiple containers running on edge servers, and a container orchestration method determines which containers should be deployed on which edge servers. This paper proposes a container orchestration method considering shared containers. These containers will be introduced in an MEC environment to reduce application resource usage, similar to a shared library in an operating system. The proposed method adopts a multi-stage grouping of edge servers to aggregate computation resource information and network information of the edge servers for efficient orchestration calculation. The formulation of the proposed orchestration method has been successfully completed, marking a significant milestone in this research. Evaluation will be conducted assuming an environment that contains 2,048 edge servers and 200 user terminals.

  • Poster: Secure NFV Infrastructure based on Software Fault Isolation Considering Multi-Tenant Environment

    Soki Koizumi, Takao Kodo, Fumio Teraoka

    MOBISYS '24: Proceedings of the 22nd Annual International Conference on Mobile Systems, Applications and Services (ACM)     650 - 651 2024.06

    Research paper (international conference proceedings), Joint Work, Last author, Corresponding author, Accepted

    　View Summary

    Network Function Virtualization Infrastructure (NFVI) enables the operation of Network Function Chaining (NFC) in a low-cost and flexible manner by realizing network functions as software on general-purpose servers. One of NFVI's security requirements is access control to packet buffers, which can be achieved using Intra-process Isolation techniques. This paper proposes a secure NFVI using Software Fault Isolation (SFI) for access control to packet buffers by inserting bounds check instructions before indirect memory access instructions. The measurement results show that the proposed method is faster than ERIM, another Intra-process isolation method based on domain switching.

  • Poster: Pub-Sub Based M2M System in an MEC Environment Considering Mobile Nodes as Compute Servers

    Research paper (international conference proceedings), Joint Work, Last author, Corresponding author, Accepted

    　View Summary

    The number of IoT devices is increasing, but applications that utilize IoT devices and their data are still developing. One reason is the tight coupling between M2M infrastructure and applications and the difficulty of handling mobile devices in a unified manner. To address these challenges, we developed a versatile M2M system called "MECM2M"that utilizes the MEC paradigm. This paper proposes "MECM2Mv2"by adopting the Pub-Sub model and redesigning modules to improve the latency and efficiency, which were issues in MECM2M. Our future research evaluates the safety of using MECM2Mv2 in autonomous driving applications.
